Abstract
Zerumbone is a naturally occurring humulene type sesquiterpene, isolated from the rhizomes of Zingiber zerumbet (L.) Smith with excellent therapeutic potential and is recognized as a valuable synthon for the construction of diverse array of natural product motifs. In this review, we intended to highlight our achievements in utilizing abundant natural product zerumbone and its derivatives for the development of pharmacologically relevant molecular scaffolds. We provided an account of the transition-metal catalyzed 1,4-conjugate addition reactions of zerumbone and its derivatives along with palladium-catalyzed cross-couplings, transition metal-based Lewis acid promoted interrupted Nazarov cyclisation reaction with substituted indoles and transannular cyclizations, photo-induced transformations of zerumbone and its epoxide.

Abstract
The reactivity of azomethines based on trifluoroacetaldehyde hydrate in the Castagnoli-Cushman reaction (CCR) was researched. The impact of the nature of anhydrides explored on the reaction route was determined. The preparative procedures for the synthesis of N-substituted (3R*,4R*)-1-oxo-3-(trifluoromethyl)-1,2,3,4-tetrahydroisoquinoline-4-carboxylic and (1R*,2R*)-4-oxo-2-(trifluoromethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine-1-carboxylic acids in gram scales were elaborated. It was shown that the trifluoromethyl group remarkably decreased the reactivity of azomethines in CCR. The mechanism for the formation of different products depending on the anhydride's nature was proposed.

Abstract
The versatile isocyanide building block Asmic, anisylsulfanylmethylisocyanide, reacts with aldehydes and ketones in a BF3·OEt2-mediated condensation to afford thioimidoyl-substituted 2,5-dihydrooxazoles. The condensation is distinguished from related base and transition-metal-catalyzed [3 + 2] processes in proceeding via the condensation of aldehydes and ketones with 2 equiv of an isocyanide followed by a molecular rearrangement that installs four new bonds. BF3·OEt2 mediates an analogous condensation of Asmic with imines to generate N-substituted dihydroimidazoles. Mechanistically, BF3·OEt2 activates the isocyanide to facilitate deprotonation evolving to a zwitterion that traps π-electrophiles in a formal [3 + 2] process. A second deprotonation-condensation with Asmic initiates a structural rearrangement involving a sulfanyl elimination-addition transposition sequence. The resulting dihydrooxazoles and dihydroimidazoles contain a thioimidate that serves as a diversification point for further elaboration.

Abstract
This review covers sixty original publications dealing with the application of multicomponent reactions (MCRs) in the synthesis of novel nucleoside analogs. The reported approaches were employed for modifications of the parent nucleoside core or for de novo construction of a nucleoside scaffold from non-nucleoside substrates. The cited references are grouped according to the usually recognized types of the MCRs. Biochemical properties of the novel nucleoside analogs are also presented (if provided by the authors).
